[Q] Camera Flash is not working ?!

HI everyone,
I bought a HTC HD2 some days ago, and there was win mobile 6.5 and android 2.2 installed. THere were many problem on the Android OS, it was very slow, the auto-rotate function didnt work, the "water scale" didnt also work correctly etc. Win Mobile seemed to work properly...
Today, I installed android 2.2 on my storage card and everything is working fine so far. Of course, WIN MOBILE is on my phones memory. Before installing it, the phone had problems with the flashlight (dual flash), simply, it did not work. Now, it is also not working, neither under WIN Mobile nor ANDROID.
How can I check that it is a hardware failure ? Or maybe its ROM or something ?
Thank you
Please, some idea ?
What level is the battery at? As I think thart below 20% the flash stops working.
What happens in WinMo when you run the camera and select flash always on and then take a picture?
THanx for the response, I really need some help.
Under WinMo occurs the same problem, the flash is not working even if I set it to AUTO/ON/OFF.
I also considered that the image quality after taking a picture and comparing it to my friends phone, is more bad than his one
PLEASE, someone help ?
Anyone has an idea ?

Hi There
I'm not aware of any "diagnostics" modes to test hardware on the device but the first thing I would do from within Winmo is install a Torch App and try and use the torch, if the Torch app initialises the flash on the back of the phone then you know it's a OS fault whereas, if it doesn't you know it's a hardware fault with the flash module itself on the phone
Here's a link to TorchButton

Let us know how you get on
Thank You very much for the reply.
But I act as a noob.
I copied the whole unrar-ed folder to my SD and to phone, in both ways, when I try to start any of those files it says:
There is no application associated with ... Run the application first, then open this file from within the application.
How to run the application ?
Can someone just download the TORCH and explain to me how to install it
Would be very very thankful.
Can someone just explain me how to install or whatever the torch on my HD2 WIN Mobile 6.5.
THanx
anyone ?
thx
Do not unpack (unzip, unRAR) the file. Just copy it to your phone (or SD card). Use the phone's file explorer and find the file. click on it, and it will install.
.cab files are cabinet files, they pack other files inside them, just like zip files - but they are used in both Windows (the computer o/s) and the WinMo o/s as a unpack and install file (obviously the file should only be run in the desired o/s).
Thank You fred_up,
I barely did it, but the flash is still now working.
I hope its only the flex cable which is not too expensive, about 10 USD !?

[Q] Script Help - App Data Sync

Hi all,
Just wanting a little bit of help with a script to sync a folder from one device to another? (main purpose is for game progress).
Over wifi if possible. even FTP would is fine.
Though the tricky thing is i want the script to check which has the latest version and only sync the newest.
Can someone give me a draft script? i can generally work out the rest.
Or even just a link to a site that can help would be great. (will press thanks!).
I can script well with VBS though linux stuff is all new.

[Q] Issues with reverse engineering APK

Im having issues with reverse engineering an apk file where the compiled apk ends up timing out with a black screen whenever its opened.
What advise would you guys have for me? I am using apktools and also tried dex2jar and jdgui(I think its called) but still not working or maybe I just cant figure out how to use eclipse properly because I'm a bit of a novice to java/android development.
